When using a handheld laser welding machine, the protective lens is an important consumable component. Proper operation and routine maintenance can help reduce lens contamination and damage, extending its service life.
Step 1: Use Original Protective Lenses
Choose original protective lenses that are compatible with your machine. This helps ensure lens quality and proper fit, reducing the risk of poor welding results caused by an incompatible lens.
Step 2: Properly Increase the Shielding Gas Flow
During welding, shielding gas helps prevent fumes and spatter from entering the welding gun. Adjust the gas flow according to the actual welding conditions. A reference pressure setting is around 12–15, but the specific value should be based on the machine's requirements and the actual welding process.
Step 3: Pay Attention to the Welding Angle
The welding angle can also affect the amount of fumes and spatter generated during welding. Adjust the angle according to the material and welding position. A commonly used welding angle is approximately 45°–60°.
Step 4: Avoid Welding Hot-Dip Galvanized Sheets
Welding hot-dip galvanized sheets can produce more fumes and spatter, which may accelerate protective lens contamination. Therefore, whenever possible, avoid directly welding hot-dip galvanized sheets unless suitable fume extraction and process controls are in place.
By following the steps above, together with regular inspections and timely replacement of protective lenses, you can help extend lens service life and maintain the stable operation of your handheld laser welding machine.
